The interest in early summer topsoil grid sampling (1.0- to 2.5-acres per grid) continues to increase, especially in traditional corn-soybean growing areas. In Minnesota alone, 30-40% of all grid soil samples are now collected in the summer months. The early summer period (late May to late June) is an excellent period of time to collect […]
This article originally appeared in the AGVISE Laboratories Spring 2025 Newsletter. Cool and wet soil conditions can limit root growth and phosphorus uptake during the early growing growing season. This is why starter phosphorus placed with or near the seed can be so effective in enhancing early plant growth and development. In small grains, starter […]
This article originally appeared in the AGVISE Laboratories Spring 2024 Newsletter. Over the winter months, we received a lot of questions about the increasing soybean cyst nematode (SCN) egg count trends across the region. Soybean cyst nematode is the most damaging soybean pest in the United States, and the problem is becoming worse. The AGVISE […]
This article originally appeared in the AGVISE Laboratories Fall 2022 Newsletter under Southern Trends The spring and early summer were very interesting to say the least. Spring rains continued well into late May and delayed planting for sugar beet, corn, and soybean throughout the southern region. By mid-May, many producers changed long-day corn maturities to […]
This article originally appeared in the AGVISE Laboratories Winter 2022 Newsletter This is the third year of our soybean cyst nematode (SCN) resistance project. Each year, we have flagged spots in soybean fields and collected paired SCN soil samples in June and September. If the SCN egg count increases through summer and into fall, we […]
Soybean Cyst Nematode (SCN) is the number one crop yield-reducing pest in soybean production. Potential crop yield loss to SCN is expected to rise as more and more populations of SCN overcome the PI88788 resistance source. The Peking resistance source is not as common as the PI88788, but it is becoming incorporated into more soybean […]
